Description
Technical field
The utility model relates to a kind of aseptic welding sheet.
Background technology
In medical treatment, the industry such as bio-pharmaceuticals and food, when needing two flexible pipes to carry out aseptic connection, often need manual in bacteria-and dust-free environment completing, adapter equipment and the welding sheet for adapter equipment were there is afterwards, this welding sheet adopts on copper sheet, is coated with one deck insulating cement, then on insulating cement, one section of serpentine resistive line is printed, finally by above-mentioned copper sheet doubling, make a copper sheet outside, insulating barrier is in centre, serpentine resistive line is in the entirety of inner side, when using, be energized to serpentine resistive line, serpentine resistive line generates heat, heat is delivered on copper sheet, whole copper sheet is made evenly to be warmed up to 200-380 degree Celsius, so make in non-sterile dustfree environment, carry out the aseptic of two flexible pipes to connect in order to possibility.
Chinese invention patent prospectus CN102672965A discloses so a kind of welding sheet, practical effect is better, but it is coated with this method of one deck insulating cement on copper sheet, need first on copper sheet, to be coated with the glue of a layer thickness at 0.01-0.03mm thickness, glue application and dry strict to the proportioning of glue, the precision of equipment and operation technological requirement, careless slightly, the defective products that bondline thickness is inconsistent, have the defects such as pore will be produced, not only can not reach in use should be effective, also has the risk of damage equipment; Meanwhile, adopt glue to need first to be coated with and then just can to carry out next process after at high temperature oven dry as insulating barrier, also there is the shortcoming such as complex manufacturing and scrappage height for a long time.
Utility model content
The technical problems to be solved in the utility model is to provide the welding sheet that a kind of result of use is better, easy to process and manufacturing scrap rate is low.
For solving the problems of the technologies described above, welding sheet of the present utility model, be made up of sheet metal, insulating barrier and serpentine resistive line, insulating barrier is attached on sheet metal, and serpentine resistive line is on the insulating layer attached, and the insulating barrier be attached to together and sheet metal penetrate by least two contact holes, by the sheet metal doubling with insulating barrier and serpentine resistive line, by contact hole, serpentine resistive line can be connected into electric loop, above-mentioned welding sheet is generated heat, and above-mentioned insulating barrier is made up of resistant to elevated temperatures heat conducting insulating film and glue.
Adopt aforesaid way, due to resistant to elevated temperatures heat conducting insulating film consistency of thickness, do not have pore, the welding sheet thickness produced is more even and consistent, and result of use is better; Adopt resistant to elevated temperatures heat conducting insulating film to substitute in the processing method of insulating cement production welding sheet also before need after coating insulating cement first to dry after just can enter the trouble of next step, not only produce scrappage that is convenient and that greatly reduce in production.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the enlarged schematic partial view that the utility model welding sheet overlooks direction.
Fig. 2 is the schematic diagram of the main apparent direction of the utility model welding sheet.
Detailed description of the invention
Fig. 1 is the enlarged schematic partial view that the utility model welding sheet overlooks direction, shown welding sheet, by sheet metal (1), resistant to elevated temperatures heat conducting insulating film (5), glue (7) and serpentine resistive line (3) composition, resistant to elevated temperatures heat conducting insulating film (5) is attached on sheet metal (1) by glue (7), serpentine resistive line (3) adopts the mode of printing post-drying to be attached on resistant to elevated temperatures heat conducting insulating film (5), resistant to elevated temperatures heat conducting insulating film (5) and glue (7) form insulating barrier (called after 2 jointly, do not mark in figure), at least two contact hole (called afters 4, do not mark in figure) the resistant to elevated temperatures heat conducting insulating film (5) be attached to together and sheet metal (1) are penetrated, will with sheet metal (1) doubling of resistant to elevated temperatures heat conducting insulating film (5) and serpentine resistive line (3), contact hole (called after 4 can be passed through, do not mark in figure) serpentine resistive line (3) is connected into electric loop, serpentine resistive line (3), because of self-resistance heating, makes above-mentioned welding sheet to be heated to 200-380 degree Celsius.
Fig. 2 is the schematic diagram of the main apparent direction of the utility model welding sheet, it has two contact holes (4).
Above-mentioned glue (7) can be the epoxy resin glue of heat conduction or pressure sensitive adhesive; Sheet metal (1) is pure copper sheet or latten(-tin), also can adopt the copper sheet of nickel plating; Resistant to elevated temperatures heat conducting insulating film (5) adopts can at the Kapton of 300 degree Celsius operational or high temperature resistant PET polyester film, and thickness is 0.005mm-1mm, and preferred thickness is 0.01mm-0.05mm.
Certainly, resistant to elevated temperatures heat conducting insulating film can also adopt the resistant to elevated temperatures heat conducting insulating film of other material except adopting above-mentioned film, and above-mentioned conversion all drops within protection domain of the present utility model.
